Unity 3 slow with motionbuilder

Unity Engine
1

Hi, I am using Unity 3 on a Pc with Motionbuilder 2011. When I swap between Motionbuilder and Unity I get an incredibly bad frame rate in Unity (less than 1fps!) so it’s unusable.

Has any one else experienced this. I am using a 4gb Amd Phenom II x6 1055t 2,8 GHz system on windows 7 64bit so it should be able to handle it! When I have Max and Photoshop open with Unity I have no issues, it’s only when I have motion builder open.

Any ideas as our tech support is stumped!??

Hi,

You probably know this but just in case, minimizing Motionbuilder when switiching to Unity will free up half of the CPUs.

Unlike most other 3D software, MB acts a bit like a game engine, always evaluating.

Cheers,
